IMPROVEMENT IN `ZPOSTOFFICE LETTERBO'X.

The Schedule referred to in these Letters Patent and making part of the same To all whom it may conce/ru Be it known that I, BIRAM O. DAvrs, ot Binghamton, count-y of Broome, State of 'New York, have invented a new and useful Improved Letter- Box; and I do hereby declare that the following is a full, clear, and exact'description of the construction and operation of the same, reference being had to the accompanying drawings, and to letters of referencemarked there on,`making apart of this specification, in whichi Figure 1 is aview, showing the out or public side place to transmit articles to be mailed; f

Figure 2 is a perspective View, shown inside the oice; and l Figure 3 shows the bottom4 and manner in vwhich theletter-box or boxes are operated.

This invention relates to a new post-oilice. arrange.- Inent, whereby letters and other articles, and their postage can be deposited quickly, safely, and separately, thus in numerous cases releasespersons from waiting, in an over-crowded oi'lice, or whenclosed, and at such times, not only a convenience to the public, but releases the postmaster from waiting on such persons separat-ely, and at the making up of each mail can attend to all at onee,'holding for postage such letters and articles that are not properly paid. Post-i age indicator is to be attached at iig. 1.

The construction and operation are as follows, which I apply by cutting and making a way through the partition or wall of the ofhce, and case it, as shown in tig. 1; and construct a series of letter-boxes, A-A

'in the notch B, and the spring E is at tbe same time depressed.

V Any person opening thel sliding door G always presents an empty box, as shown in figs. 1 and 2, and carries away the contents that have previously been deposited, as shown in box 1; and at the making up of each mail, 0r when the sliding boxes are filled, the postmaster depresses the springs .D and F, at H,

which allows the series of sliding boxes to slide back,

and presents the contents to be distributed, and leaves the boxes in a position ready to be tilled again.

. vI claim the combination and arrangement ofthe series of sliding letter-boxes, having guides B B, with the detent-pawls D and E, and the actuating pawl F, Operated by the sliding door G, substantially as and for the purposes herein described.

BIRAM DAVIS.
